(01. 214-16 This invention -'relates to improvements in apparatus for performing finishi-ng operations onifioori-ng or the like, and has for an object the provision in apparatus for finishing parquet flooring blocks or the like, wherein said blocks are moved alon the trackway at a predetermined rate, an unloading station adjacent to said trackway, and mechanism carrying a plurality of engaging members moving in a path angular with respect to the path of movement of said-flooring blocks, the result of both said movements ef- 'fecti-ng the eiecting of said blocks into said loading station.

per se is not shown in Figure 1 but maybe seen in Figure 3, to be presently described;

Figure 2 is a plan view of the mechanism shown in Figure l, and in this figure, the unloading station per se is not shown;

Figure 3 is an enlarged plan view of a portion of the mechanism shown in Figures 1 and. 2, which includes an unloading station and shows details of the unloading mechanism which is adapted to discharge the blocks from the dolly in o said unloading station;

Figure 4 is an elevation of the arrangement 7 shown in Figure 3;

Figure 5 is a perspective view of a parquet block, such as is carried on the dollies; and

Figure 6 is a perspective view of one of the 7 Beferring to said drawings, a trackway ill oomprised of a supporting bed I I has mounted thereon rails l2 and l2a. This trackway issupported on uprights l3 and carries a plurality of dollies l4, each-having flanged wheels [5 engaging the rails. The dollies M are secured together by links I6, and each dolly has its body portion formed. to accommodate a parquet'flooring block 11, such as that shown in perspective in Figure 5.

Means (not shown) is provided for moving said dollies along the traekway In at a predetermined rate and the parquet blocks IT on these dollies, as they pass along the trackway, successively encounter'rotary tools 18, I 9 and 20, which are v 2 e driuen by zpowertmeans. {These iaotarytoolsrmay be in the ferm on-brushes or any other form, for 'pnoducing a -desined :finish on the parquet blocks, and they may be-drl-ven in different directions relative $9 :each other by means of rotating shaft :2 l. For example, the shaft 2| may carry a-pulley 22 bolted to. the pulley .2-3 {on the tool 18, so as to causethe tool to rotate in a clock-wiseydl-rec- .ticmas viewed from above. 7 I

Theznext tool 1:9 maybe driven by a pulley 2-4 so belted to pulley 25 (on the shaft of the tool 19 as to cause th -pill-1 .17 to rotate a counter-clockwise vdirection, ,as seen from above, which direc- $11011 is opposite from the direction -:of rotation of the tool l8.

Athird tool 20 may be so bolted to the pulley on the shaft Zil'that its spindle pulley :21 rotates in .aiclockwise direction, as seen fromiabove.

From the above, it can he seen thatasy-the dollies carrying the parquet blocks pass beneath these tools, they are polished first in one direction, next, inrtheoposite direction, and then in the first direction-a ain.

Referring now :to .Figures 3 and 4, a frame member 28 has-dependin portions, two of which are shown :at 12:9 and 32, and like pontions spaced apart therefrom and in alignment therewith, as seen in figure 4. These portions are formed integral said frame and include bearings near their upper: ends. Rotatably supported in the bearing portion .29 and the portion alignment therewith is .a shaft 133 which carries sprockets 34 and :35 in spaced relation to each other.

A second shaft 36 is journaled in the "portion 32 and the portionzin alignment therewith and carries sprockets 51 and 31., All of these sprockets are of the same size and have the same numherof-teetn. g 7

In Figure 3, the "frame member 28 has been omitted iorthesake of clarity. However, it will :be understood that the shafts 3.3 and 36 are journaled in this frame member, as above described. A link chain 38 is placed about the sprockets 34 and 3! and likewise a second link chain 39 is placed about the sprockets 35 and 51.

A bridge member 40 positioned between the chain has one end secured to the chain 38 and its other end secured to the chain 39. A second bridge member 4| and a third bridge member 42 are mounted on chains 38 and 39 in the same manner and these bridge members are preferably spaced equidistant from each other.

Although only three bridge members are described, it is obvious that we may use a greater orless number of bridge members without departing from the spirit of the invention.

Secured to the bridge member 40 isan engaging tion is substantially the same as the angular dis 1 I posal of the mechanism (Figure 3) with respect to the path of travel of the dollies carried by par- 1 quet blocks, as will hereinafter be explained.

Similar engaging members Bland Bl areisei cured to the bridge members llijajnd 42, respectively, and they function in the same manner as does the engaging member 59.

The shaft 36 carries a pulley 41 which maybe,

connected by means of a belt to a pulley. on a prime mover (not shown). As the pulley 41 rotates, the sprockets 51 and 31 rotate therewith and drive the chains 38 and 39 and these chains,'ih turn, drive the sprockets 35 and 34, respectively. This causes the engaging members Although we have herein shown and described by way of an example, apparatus for performing work on the surfaces of parquet flooring blocks and ejecting said blocks onto an unloading station, it is obvious that many changes may be made in the arrangements shown and described within the scope of the following claims.

, 7. What is. claimed is:

1. Conveyor mechanism for parquet flooring blocks and discharge apparatus therefor comf rising, a. trackwayr a series of dollies moving l6 and I1 moving successively into the range of said members. The mechanism shown in Figures 3 and 4, as can be seen in Figures land 2, is

angularly disposed with respect to the movement of the dollies carrying the'parque't flooring blocks along the trackway= I0 and this movement is so related to the movement of the engaging members along their angular path that the resultant movement of v the blocks I1 is laterally along a substantially straight line.

- Referring to Figure 3, an unloading station 52 may consist of a platform 53 suitably supported adjacent to the trackway 10, which is provided with an upright side wall 54 joined by upright end walls 55 and 5 5. Slots51 and 58 are formed in theend'walls to facilitate the removal of par quet blocks from said unloading station.

As shown in Figure 6, the dollies have their sides 14a open and-their sides lib-have slots I40 formed therein. The dollies are each provided with edges Md and each of these edges is provided with a longitudinal slot on its inner edge. The dollies each have edges I 4e which are disposed on the sides opposite the edges Md and each edge He is provided with a longitudinal tongue which extends inwardly. The slot and tongue on each dolly are adapted to be slidably engaged respectively by the tongue and the groove of the parquet blocks'lL- The engaging members 59, 60 and GI are of such length that they clear the sides' Nb of the dollies and engage and push the blocks lI laterally from the dollies and into the unloading station In Figure 3, the parquet block "ads shown as moved a little over half way out of the dolly by the engaging member 59. As the engaging member 59 continues its movementdiagonally to the right, as seen in Figure3, the dolly is moved upwardly, with the result thatas the engaging member 59 passes out from the surface of the dolly just clearing th "upper right-hand corner thereof (the upper end of the edge Nd) the block Ha is completely ejected from the dolly and falls to the platform 53 of the unloading station. As the next succeeding dolly-approaches the unloading station, the parquet block [1 carried thereby likewise is ejected therefrom by the engaging member 6|. Then, the next succeeding dolly has its parquet block ejected by the engaging member 60, and this continues to repeat as long as the device isoperated.

therealong ata {predetermined rate, each dolly being adapted to support a parquet flooring block, whereby the-latter may be laterally ejected therefrominto arr-unloading station adjacent to and below the level of said trackway, said station having boundaries extending vertically on three sides, the other side being open toward said track way, the two boundaries adjacent to said open side having-vertical slots formed therein to .facilitate theremoval oi-stacks of said blocks from said unloading station and a series of engaging membersimoving along a path forming an acute angle with the path of movement of said dollies andadapted to push, eject and stack parquet blgcks into said unloading station via saidopen sle.

2. Conveyor mechanism for parquet flooring blocks and discharge apparatus therefor, comprising a trackway, a series of dollies. connected together and moved therealong atga, predetermined rate; each of said dollies having an open side, a closed side adjacent thereto and carrying a slot, 2. second side adjacent theretoand carrying a tongue, and a side opposite said open side; said slot being adapted to be engaged by a tongue on a parquet flooring blockand said tongue being adapted to be engaged by a groove in a parquet flooring block, whereby such blocks may be;s1idably removed from the dolly via said open side, an unloading station adjacent to and having an opening facing said trackway,,and a series ,of engaging members moving along a path angularly disposed in an angle of less than with respect to the path of movement of said dollies, said members being adapted-to push and eject said blocks from said dolly and into said unloading station via said openside as eachdolly is traversing said open side.
